Contributing to the community—through both research and reviewing—has been one of the most fulfilling aspects of my academic career. Many thanks to the organizers, colleagues, and students who make CCS such a vibrant and rigorous forum for computer security research!

#IUBIK leverages memory tagging (MTE) and pointer authentication (PA), available in #ARM CPUs, to efficiently and effectively isolate attacker-controlled input from security-critical data in the kernel heap.

📢 Last week, Brown Secure Systems Lab (SSL, gitlab.com/brown-ssl) was at the IEEE Symposium on Security and Privacy (S&P) 2025, where we presented our latest work on hardening OS kernels against attacks that (ab)use heap-based memory-safety vulnerabilities.

#IUBIK hardens OS kernel code against attacks that (ab)use memory errors via means of: (1) attacker-controlled input isolation, (2) memory tagging (ARM MTE), and pointer encryption (ARM PA).

📢 Last week, I had the pleasure of visiting the beautiful University of Delaware (@udelaware.bsky.social) to speak about supply chain security, and reconnect with friends and colleagues!
